We consider methods for estimating the means of survey variables in domains of a finite population, where sample sizes are too small to obtain reliable direct estimates. We construct generalized compositions from the direct and traditional design-based synthetic estimators and propose the methodology for evaluating their coefficients. This methodology measures similarities among sample elements and estimates of the domain means. We propose the compositions for two cases of auxiliary information: domain-level characteristics are available; true means of auxiliary variables are available for the estimation domains, and unit-level auxiliary vectors are known for the sample elements. In the simulation study, we show where the generalized compositions improve the traditional synthetic and composite estimators. 相似文献

We study competition as an impetus for firms to reposition—to abandon their current positioning strategy and adopt a new one. We predict that as a strong firm moves closer, competition erodes the profitability of situated firms and prompts them to reposition. We expect this effect is pronounced the greater difference in competitive strength. However, we expect that countervailing forces exist such that the viability of alternative positions and the opportunity cost of abandoning a current position mitigate this effect. Evidence from a natural experiment in China's satellite television industry supports our hypotheses. This research adds to the existing literature on repositioning, which emphasizes the phenomenon as opportunity‐driven, and to the competitive interaction literature, which typically does not distinguish between noncounterattack strategies.

鉴于负债的确认和核算是自然资源资产负债表编制的重点和难点,文章以国内外矿产资源资产负债的存在及其表现为线索进行分析与探讨,研究矿产资源开发产生负债运行机理和负债核算范围及内容等,揭示出矿产资源在其负外部性作用下形成负债的机理,并根据负外部性效应将矿产资源开发产生的负债划分为耗竭性负债、生态环境负债和安全负债,同时将耗竭性负债、生态环境负债和安全负债的核算范围与现有法律法规相衔接,提高负债核算的可操作性和可推广性,为自然资源资产负债表编制和维护国家所有者权益提供技术支撑。 相似文献

AbstractThe paper presents a reform proposal for the operations of the European Central Bank (ECB) whose purpose is to create a common set of risk-free assets for financial institutions operating in the euro area (EA), which is the necessary condition for having a single internal financial market. The proposal does not require the introduction of changes in the existing European Union treaties. The effects of this reform on the debt dynamic of EA member countries permit a revision of the existing fiscal rules. With the help of some simulations, it is shown that maintaining compliance with the European treaties, the reform of the ECB operations and revised fiscal rules would transform the current fiscal deflationary stance into a reflationary one. Some implications for aggregate demand and growth for the EA are briefly discussed. 相似文献

This article analyses the anchoring of inflation expectations of professional forecasters and consumers in the euro area. We study anchoring, defined as the central bank's ability to manage expectations, by paying special attention to the impact of the ECB inflation target and ECB inflation projections on inflation expectations. Our analysis indicates that in the post-crisis period longer-term inflation expectations have become somewhat more sensitive to shorter-term ones and to actual HICP inflation. We also find that the ECB inflation projections have recently become more important for short- and medium-term expectations of professional forecasters and at the same time the role of the ECB inflation target for those expectations has diminished. Overall, our analysis suggests that in recent years inflation expectations in the euro area have shown some signs of de-anchoring. 相似文献
